Description

A kind of energy-saving air conditioning system
Technical field
The present invention relates to a kind of energy-saving air conditioning system, belong to air-conditioning system technical field.
Background technology
Equipment for annual all-weather coolings of needs such as Large-scale Data Rooms, communication machine room and industry and control machine room and Internet data centers (IDC), mostly adopt the air-conditioning system of steam compression type refrigeration circulation, because the power consumption of compressor in air-conditioning system occupies the overwhelming majority of air-conditioning total power consumption, the working time that therefore how to reduce compressor becomes the main direction that reduces energy consumption of machine room.Improving under the prerequisite of air-conditioning system refrigerating efficiency, if utilize four seasons Different climate condition, indirectly or directly utilize outdoor cold source to reduce the humiture of indoor equipment, reduce compressor operating time, thereby can reduce the energy consumption of whole machine room.
Utilize at present the method for outdoor new wind to have following several: (1) indirect utilization outdoor cold source: in chamber, between inside and outside, to increase a heat exchanger, inner air and outer air is directly contact not, by heat exchanger mediate contact, reach the object of heat exchange, this method can avoid outdoor unclean air to enter machine room, guarantee the cleanliness factor of machine room, but at transition season, due to the existence of heat transfer temperature difference, cooling effectiveness is poor, and energy-saving effect is not obvious.(2) ethylene glycol is naturally cooling: at indoor set, increase a refrigeration coil, by water pump, the outdoor glycol water being cooled is pumped in economic coil pipe, carry out heat exchange with indoor return air, reach the object of refrigeration, the weak point of the method has: a. is confined to water chiller; B. ethylene glycol solution has corrosivity, to pipeline cleanliness factor, requires very high; C. the resistance of ducting is large, and blower fan power consumption increases, and needs to be equipped with water pump simultaneously, causes the power of complete machine to rise, and further increases energy consumption; (3) fluorine pump natural cooling source system: fluorine pump single system is under two kinds of operational modes in mutual handoff procedure, and compressor can cause flooded starts, and cavitation erosion appears in fluorine pump, fault rate is high, and dual system operation need to increase by two device costs, and transition season fluorine is difficult for condensation, and refrigeration is not obvious; (4) directly utilize new wind: outdoor new wind is introduced directly into after simple filtration treatment indoor, to heating calculator room equipment lower the temperature.The method cannot be controlled humidity, and outdoor environment is dirtier, when dust content of air is larger, cannot directly apply; When outdoor temperature is low in addition, directly introduce new wind and can cause condensation problem.
In order to overcome the defect that the naturally cooling air-conditioning system of new wind is higher to outdoor air environmental requirement, Chinese patent literature (CN202547054U) discloses a kind of new wind nature Cooling Air-conditioning System, comprise: the indoor air draft air-valve by the circulation of air in indoor to the wind cyclic space, air in this wind cyclic space is discharged to outdoor outside air draft air-valve, mixer selector valve by the circulation of air in this wind cyclic space to mixed wind space, by the outdoor new distinguished and admirable new air-valve that leads to this mixed wind space and this is indoor in circulation of air to the air conditioner in machine room air returning valve of air conditioner in machine room, the water filtration space that the air that in mixed wind space, circulation is come is filtered, to the bag type filtering space of filtering by the air coming from this water filtration spatial flow, the wherein air inlet of this air conditioner in machine room and this bag type filtering space UNICOM.
Above-mentioned patent has been carried out clean and has filtered and can regulate indoor air humidity outdoor air, but still has following problem: (1) above-mentioned air-conditioning system cannot meet the refrigerating operaton demand of annual Various Seasonal.(2) above-mentioned air-conditioning system is provided with water filtration space, although can regulate the humidity of air, during this system works, thereby water can be blown into the normal operation that affects equipment in air conditioner in machine room, therefore has potential security risk.
In sum, how by energy-conservation mode, make full use of refrigerating operaton demand that outdoor new wind, indoor return air meets annual Various Seasonal to guarantee that indoor temperature and humidity are the technical barrier that also there is no solution in prior art within the specific limits.
